But the rich will have cheered Mayor of London Sadiq Khan’s call to the protesters to allow a return to “business as usual”.

Business as usual means continuing the system dominated by the 100 corporations responsible for over 70 percent of the world’s greenhouse gas emissions since 1988.

It means allowing the oil giants, the bankers and the bosses to continue putting profits before people.

It is this system that needs to be confronted, not championed.

Nothing we can do as individuals will ultimately matter as long as capitalism’s ruthless exploitation of people and the planet remains in place. As Greta Thunberg, the student climate activist, said on Monday, “We can’t focus on small things.

“Basically, nothing has changed.”

Dominated

We cannot halt climate chaos in a system dominated by billionaires, and we can’t do it without action beyond national boundaries.

And for the movement to succeed, it has to be anti-capitalist, opposed to racism, and internationalist.
